Switching to Directv from Dish and have a few questions

Hello,

Here is my current setup
Mythtv 0.25.2
2x Dish network VIP-622 receivers
2x HDPVRs
commandir III

I am interested in switching to directv. It looks like their current HD
receiver is the H24.

Questions:

1) Any there concerns with the H24 and mythtv? With the HDPVR, I would
need to utilize the component output for all recordings. Is the output
restricted for component on any channels?

2) I am hoping to use the network channel change script
http://www.mythtv.org/wiki/Controlling_DirecTV_Set_Top_Box_(STB)_via_Network
and eliminate IR altogether on the backend. Are there any known issues
with the H24 and network channel changes?

Thanks in advance,

Michael

I use HD-PVR's to capture the output of H24's with MythTV and it works
fine for me. I don't know of any restricted channels, but I probably
only record a dozen or so channels when you get right down to it and I
have never tried it with PPV.

My H24 only has a coaxial SPDIF output, so I had to buy a media
converter in order to capture 5.1 audio. Stereo works fine.

I use an earlier version of the directv_http.pl that works very
reliably for me. By inspection, the main differences between the
script I am using and the one currently in the Wiki appear to be
logging-related, so I don't expect you will have any issues. To use
the script, I have my network DHCP server set to give the STB's a
fixed IP address and that works well.

You may have to tinker with delays in order to get everything to work
reliably. I currently need a 6 or 7 second delay after tuning my H24
before exiting the tuning process in order to avoid getting 'B' files
from the HD-PVR. You can call the script directly with the desired
delay or write a wrapper script with a 'sleep' statement after
returning from the directv_http.pl script.

IIRC, there may be some additional information in the mailing list
archives - just search on 'directv'.

Thanks for the response. The installer didn't have any H24's. After 2
visits, they finally offered me H23's. These do have SPDIF.

Thanks. 1 second seems to be working for me.

I also modified the script to turn on the receiver if it was already off
in the event of a channel change.

It was a much easier integration than my previous experiences using IR
blasters.

I wish they still had this network interface on the H25's. I don't
believe you can manage them the same way even with the whole house
network kit.
